POWER SUPPLIES
The LMH6517 was designed primarily to be operated on 5V power supplies. The voltage range for V_CC is 4.5V to
5.25V. A 5V supply provides the best performance while lower supplies will result in less power consumption.
Power supply regulation of 2.5% or better is advised. When operated on a board with high speed digital signals it
is important to provide isolation between digital signal noise and the LMH6517 inputs. The SP16160CH1RB
reference board provides an example of good board layout.
Of special note is that the digital circuits are powered from an internal supply voltage of 3.3V. The logic pins
should not be driven above the absolute maximum value of 3.6V. See DIGITAL CONTROL for details.
